Dear eCognition boffins
I really like the create subset algorithm as it allows for automation and parallelization over very large regions when using eCognition engine. I do not like using tiles as there are often edge effects (especially when working with DEMs). Subsets allow for creating an overlap among subsets and the resulting images (DEMs) can be mosaiced to produce a seamless product. However, I am currently doing the mosaicing outside of eCognition (output DEMs for individual subsets and then mosaic with blending). This is a bit of a schlep and I notice that when running the subsets on the engine the stitching option is available to stitch the subsets? Does it stitch the outputs (images)? If so, how does it handle overlapping areas?
I guess I can just experiment and try to figure it out, but I thought I would rather save time and ask! :-)
